Yuhong Holding Group has more than 35 years experience for steel pipe and tube , fin tube , main application for Petrochemical , Oil refinary, Furnace, heating, boiler, heat exchanger, air cooler,.., till now YUHONG brand products already exported more than 85 countries, which like UK, ITALY, SPAIN , USA, MEXICO , COLOMBIA , BRAZIL, SAUDI ARANBIA , OMAN, QATAR, U.A.E, KOREA, ...., YUHONG brand already won good reputation in the market .
Studded tubes are commonly used in heat exchangers and boilers. The studs on the outside of the tube increase the surface area, which improves heat transfer efficiency. This makes studded tubes useful in applications where heat exchange is critical, such as in industrial processes, power generation, and petrochemical plants.
